This linvention relates to means for eX- tracting 4.dust froniand settling fur, 'hairor thelike andthe main object thereof is to enable the operation or .operations to 'be elfected Without detrimental effects on :the loperatives and more quickly than hitherto.

'I attain this object by vthe means illus trate'd in the accompanying itwo sheets of drawings, .wherein- VFiglre `1 isfa side elevation ot a machine forxfextracting dust `and settling fur, hair 01 ,the like.

Eligure :4; is, a perspective view of `a detail andfllustrates 'a .modcatonjleferringio rvFigures 1 to 3 ot the draw.- ings, .in the construction shown therein, I Iprovide a chamberv 1 having yan inlet 3 through which the fur, hair or thelike is 'blotvn'. ATWO Vdrums arennounted on hori- :zontal trunnions 4l and adapted to be rotated towards each other, these drums `being ,arranged s ilde by side, and forming the botltorn for apart of the bottom ofthe cham- -ber 1. Y

TheI` drums are arranged asnear together as is convenient for the passage ot' tur, hair vor the like .bet-Ween them Without rendering possible the escape .of an inconvenient amountl oi air between them. The 4peripheral surfaces 5 vof the drums are formed of.

gauze or other suitable'lmaterial adapted to vacta-s a sieve 4to prevent fur,rhair orthelike Vfrom passing'into the interior Yof the drum, but va'llow the passage of dust thereinto Where the jsaid drums do `not `form the Whole yof the bottom of the chamber, suitable members, such as laths 6 having strips 7 of flexible material, for exampleleather, attached tothe upper sides,I are provided to complete the said bottom.

Each ,drum has eight impertorate radial vpartitions 8in its'interior extending lfrom oneend to the other end thereby dividing `the interior of the drum into eight cylindersectonlike compartments 9 .whichz are. completely shut off from 'one another. lThe curved `side of .each compartment 9 is -formed byA a .cylinderfsectorlike part of the peripheral sieve, surface `5 of the drum.

,The .en ds 10 -of ythe drums .are Vformed closed .and the other ends areopen and lie in close Contact With the side 11 otthe chamber .y l"

1. The side 11 is provided with Vsector-like parts 12, one for each drum, disposed above the axes ot' the drums andfconnected by conduits 13 and 14 to an air-suction tan 15 or other suitable ,suction means. Where the pressure of theA air Wliiclrbloivsthe fur,hair or the like into the chamber ,1 is sufficiently high, the conduit Ul-mayjlead to atmosphere. In all cases dust interceptingmeans'ispreterably provided 4to catch theV dust after it y has passed through theconduit 14.

`In operation, as the drumsl rotate, one or two of the compartments 9 of each drum come linto communication with :the corresponoling portf12." 4The vcempartment 9 or compartments 9l'momentarily in communica' tion with the vport 12 .are hoyvever always situated higher than the place Where the .pe-

ripheri'es -5 of theffdrums"lienearest together. Therefore any Vdilerence of ,pressure eXist- Ying between the interior ot' thecha'rn'ber 1 and the conduit 14 acts only on A'thecompartment 9 or compartments 9 communicating with the-port 12. i

ber 1 settles and falls'on '.to those parts of the peripheries 5 `of the drums which are moment arily situated higher than the ysaid place and are causedto adheretogthose parts Vofthe sieveflikeperipheries 5 ywhich lbelong SO Fur, hair orl the like blown int-othe chamto the compartmentst) momentarily in .com f Ymunication with the ports 12,the dust-'being drawn through the said parts, ot' the lperipheries 5 into the said compartments 9 and from thence through the lports 112 into `the conduits 13 and 14. As the drums cont-inne to vrotate the said parts of the peripheries .5 move towards each o'therand pass to'the undersides of the drun1s,"an,d are replaced first vnamed parts v2of the peripheriesl' `move towards vthe lundersidesot the drums, :the compartments 9 of which they rform 'a portion come out of communication with the ing on the outer yand inner si'desof'thelfpe` ripheries V5 become equali'zed and thelfur, `hair or the'like VAlias settled o ngthe one drum meets andl clingsto the tur, hair y.9.5 by other parts ofthe peripheries 5.

A closed chamber 16 is provided beneath the chamber latoV receive the webct haii, fur or the like as it leaves the drums. K

In order to prevent or reduce the passage for example by means of pulleys 19 provided on the trunnions 4 and driven by a rope 2O passing over a jockey pulley 21 and over a driving pulley 22, the latter being mounted on a shaft 23 provided with tast Y and loose pulleys 24 and 25 A sliding door 26 is provided on the cham" ber 16 torthe purpose of removing thev fur, hair or the like therefrom.` Inspection windowsimay be provided on the chamber 1.

c Furthermore a door 27 may be provided on fas lthecha'mber 1 for obtaining access thereto.'

lt will be appreciated that more than one pair of drums may bel providedl Y In lieu of providing more than two compartments in each drum, a diametrical platform'29, Figure 4 ymay berarrangedin the drum to extend trom one end to the other to divide-the interior of the drum into'two compartments, the Aplatform 29 being art ranged,'for example by the action of gravity,

' to remain stationary in thedruniwliilst the drum is rotating and thereby out Voft the klower compartment of the drum from the pressure existing in the chamber or the said pressure and the reduced pressure acting to draw the dustand settle thefui', hair or thelike.

In the modification shown inFigur l the sieve like periphery 5 of the drum is supported by anV imperforate disc. atgone end and *byV a spider at the other end,` where the Vport 12 and exhaust orescapeconduit 13varesituated,ythe disc and spider being Y' lixed to the drum shaft 82 mountedl in suitable bearings and provided with means,

such ,as a :pulley 19 for rotating the drinn. The platform- 29 has a semi-cylindrical member 33 situated at the open end of the drum and arflange 34 situated at the closed A Y Vend of the drum, the drum shaftV 32 passing through the member 33 and flange 34 and `thereby supporting .theplattori'n.V The mein-v ber 33 is provided with an extension 35 ino'i trom the chamber 1 into the chamber tended to cause the centre of gravityfof the platform 29,member 33 and lange'-34'to lie below the shaft 32 and thereby `insure that the vplate remains in a horizontal position whilst allowing'rotation ot'thedrum.

If desiredbothrends of the drum or druins maybe open and ports communicating with atmosphere or with suction means bepro- V vided at both of the said ends. n
